1b c/ZZ whom, t may concern: I

Beit known that I, FELIX PAGNON, a citi- Zen of France, residing at Lyons, France,have

which I have made application for a patent in France, numbered 282, 695,dated November 3,-

My invention consists of a bonding or interfltting brick or tile of special form decorated on one of its faces or upon its two faces and capable of being used without the use of yZO plaster, cement, mortar, and any other material tempered with water. In the construction of partitions and other works 'it consequently avoids the use of coatings of these materials covering the partitions themselves and enables works thus constructed to be used immediately.

The accompanying drawings show the arrangement of these new bricks or tiles and the method of assembling them.

Figure l represents a'A face view of three square bricks as placed together. Fig. 2 shows to a larger scale a transverse section on the line 1 2 of Fig. l.

The square or rectangular brick shown in Fig. l has formed in two of its adjacent sides channels or grooves A A and upon Ithe two other sides tongues or projections B B for the purpose of interitting or bonding, as seen in section at Fig. 2. The tongues or projections and the channels or grooves have somewhat the same trapezoidal section; but although the small base ct b of the tongue lits exactly the base of the channel or groove its larger basey leaves a certain amount of play c c, which facilitatesv the assembling. Further,

the small faces e c, which limit the visible.

faces of the brick, are inclined inward, thus forming a small space which adj oins the space c. The small base a b ofv thetongue or pro-` jection and the bottom of the channel or groove are each provided with a small semicircular groove, the junction of which forms a cylindrical hollow cl. The objects of these forms are, first, in constructingpartitions upon relatively narrow bases to prevent the irregularities Vwhich would result from imperfect contact of large surfaces and to assure the junction of the visible faces of the bricks; second,v to superpose exactly these faces in the same plane by the exact adjustment ofthe part ct b in the bottom of the channel or groove, and, third, to consolidate, when desirable, the whole wall and to render it water-tight by the introduction of a plastic material in the spaces c d c without this material showing upon the visible faces of ,the bricks.

These bricks maybe assembled with their meeting edges in straight lines or so as to break joint, their two faces may be polished,

enameled, and decorated in course of manufacture and remain bareafter the construction ofthe walls, or they may be assembled and without any previous coating they may be covered with thin boards or wall-paper, as desired. These bricks enable in every case a rapid construction without any inconvenience and the immediate use of the works to which they have been applied.

Having fullyT described my invention, what I claim, and desire to secure by Letters Patent, is` i l. A brick having a tongue extending from one of its sides and a groovein its side opposite thereto, said tongue being adapted to interlock with the groove in the contiguous block, the side walls of the tongues tapering and the side walls of the grooves tapering to a greater degree to provide a space. between the walls of said groove and said tongue, substantially as described.

2. A bonding-brick having a trapezoidal tongue or projection on one. ofv its sides the smallv base of which is of size to fit the bottom of a trapezoidal channel or groove formed in another of its sides; the said small base and bottom of the channel each having a semil circular groove, and the sides 0f the trapezoidal tongue andV channel being connected to the outer faces of the brick, by means of short inclines, substantially as herein shown and described,

3. Abrick havinga tongue extending from one edge thereofwithinclined side walls and surfaces at the base of said tongue inclining forwardly toward the side of the brick and a Vgroove A in the opposite edge of the brick having corresponding bntreversely-inclined walls and surfaces, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
